' pockets 8 are correspondingly elongated for permitting travel of therespective roller 6 during operation. The rollers, 6 rest upon the uppersurface of the track or way and sustain the hangers which in turnsustain the door, and, to limit lateral shifting of, the door, duringits .edgewise travel,,a roller 9 is disposed To all whom it may concern:

Be it'known that I, PA'UL M. BEARD, residing at St. Louis, Missouri, andbeing a citizen of the United States, have invented certain new anduseful Improvements in Car-Doors, of which the following is a full,clear, and exact description, such as will enableothers skilled in theart to which it appertains to make and to use the same, reference beinghad to the accompanying draw-i ings, which illustrate the preferred formof the invention, though it is to be understood that the invention isnot limited to the exupper edge of the door contiguous to each bracket 5and beneath the web of the Z section, being positioned for at timesengaging the inner surface of the depending outer flange, of the Zsection, and thus limiting outward lateral 'play of the door. It is. to.be' observed that necessity for providing means for preventing roller 6from leaving the track or way laterally is thus obviated, and at thesame time frictional contact of the door 3, With either the side wall ofthe car or the said depending flange of the Z section, is prevented.'Each roller 9 may be connected tothe upper-edge of the door in variousways, but preferably by annpstanding spindle or shaft 10 formed integralwith or fixed to a U shape connecting plate scribed. as it is obviousthat various'modifications thereof will occur to persons skilled. in theart. p

In said drawings: Figure 1 is a view in side elevation of a fragment ofa car illustrating an embodiment of the present invention appliedthereto. Fig. 2 is an enlarged, detail, fragmentary View illustrat ingone of the hangers in elevation. Fig. is a vertical sectiontherethrough,taken on the plane indicated by line 3-3 of Fig. 2. Fig. 4 is ahorizontal section therethrough, taken on the plane indicated by line4-4 of Fig. 2. Fig. 5 is a detail fragmentary view of a furtherembodiment of the invention. Referring to the drawing by numerals, 1 isa side wall of a car formed with a door; Way 2, adapted to be closed bya sliding door 3 suspended from a. track or way extending under above,across, and beyond the door-way one block 12 for The said trackpreferably consists of a 2' block being formed With an inwardlybevsection- 4 having its Web disposed horizon- 'el-ed ordiagonal edge 12terminating at its tally and its inner flange upstanding and inner endin a straight portion 12'. bolted or otherwise suitably secured to thesidewall f the car. Bolted or otherwise fixed to the door 3, near theupper edge thereof, are hanger brackets 5, each comprising av plateengaging the outer surface the door 3. I

The upper end of each shaft extends roller 9 into a position forengaging'the inportion of Z section 4,'there being each shaft 10, andeach path of travel of the rollers 9, a wearing '9. Any suitable closingwedge brackets l4,14c may be provided for engaging and confining thelower edge of the door 3.

'In operation, the door 3 is shifted edgevWise to and from a positionclosing the doorway, and, in traveling outwardly or to an open position,the shafts 1O slide longiplate and a housing extending laterally towardthe car from the upperend of the arm and over-hanging the web of the 2section comprising the track. In each of said houslaterally extendingbearing members] engaging guiding pockets 88 formed in the oppositewalls of the housing. The housing isrelatively narrow foraccommodating'the width. of roller 6, but, as clearly indicated in Fig.2, the housing is elongated in the direction of the travel of the door,and the from the same and then the door moves 7 edgewise practicallytree from friction, being sustained by the hangers 5 and rollers 6 en 'a'irn the track or wa and retained h o against frictional contact withcontiguous parts by rollers 9. In closing the door, the

horizontally and revolubly connected to'the 5 l1 inclos'ing the upperedge of and riveted to.

Above: the doorway-2, 'and extending along the;

strip 13 may be provided forming an inner limit for the edgewiseshifting of the rollers tudinally of wedge blocks 12, until freed alimited amount of independent Her edge of a Wedge block 12 fixed to theis moved into ,a closed position,

' closed position, the shafts 1O arrive jamb extends outwardly at eachside of the doorway, and the door 3 is freely movable between thedepending flange of Z section 4 andthe strip 15 at one side of the.doorway until theshafts 1O engage wedge blocks 12, whereupon-the door iswedged laterally over into firni contact with strips .15 so as to beheld against play during transit. The straight edge portions 12 whichare engaged by shafts 10 when the door, is complctely closed obviate anytendency of the .door to ride edgewise would exist if the shafts 10 wereleft in enagement with inclined or beveled surfaces.

b Each roller underlaps the respective block 12 which its shaft engages,thus largely obviating liability of vertical rocking of the movableparts. with two distinct sets of guiding elements, being the rollers 9,which guide the door when loose'and-free to have limited lateral play,and the shafts 10, which guide the door to a tightly closed position.

The shaft 10 which upstands from the upper edge of door 3 may becarried, as indicated in Fig. 5, by an. angle plate 11 which is fixed toor formed integral with bracket 5, plate 11 extending across the upperedge of and engaging the door. Obviously additional means of attachmentof plate 11 to the door 3 may be provided, but usually its connectionwith bracket 5 is smithcie'nt. A fillet or web 11" may be provided forstiffening the connect-ion between the horizontal and vertical legs ofplate 11*,

What I- claim is: I

1. In a door structure, the'combination, with a track, a door hangerengaging the same, a door sustained by said hanger, a shaftupstandingfrom the door, and a wedge block disposed in the path of theout of place, such as The door is thus provided.

Copies of this patent may be obtained for five cents .each,

shaft for effecting lateral shifting thereof I during edgewise travel ofthey door and a roller coaxial withtlx: shaft and disposed forunderlapping the wedge block.

2. In a door structure, the combination, with a track, of a hangerengaging thesame,

a door sustained by saidhanger, a wedge block sustained by saidtrack andhaving a diagonal edge, means upstanding from, the door in position forengaging said diagonal edge and being shifted laterally thereby,

ingedgewise travel of the door, and a roller carried by said upstandingmeans and adapted'to underlap the wedgelblock.

3. In a door structure, a dodr hanger engaging the same, a doorsustained by said hanger,

door in position for engaging vone of the and correspondinglyshiftingthe doordur- Y a Z section track,

a horizontally disposed roller carried at the upper edge of the flangesof the track section, a-closing wedge for the door out of the path ofthe roller,

and guiding means carried by the door ad ditional to'the roller adaptedto engage the closing wedge.

4:. Iii a door structure, with a: track and a hanger engaging the same,of a door sustained by said hanger, a shaft fixed to and upstanding fromthe door, a horizontally disposed roller journaled'on the said shaft,and in the path oftravel of the shaft for shifting the shaft laterallyduring edgewise travel of the door, the wedge block being out of thepathjof the roller.

5. In a doorstructure, the combination, of a 2 section track, a doorslidingly sustained thereby,'a shaft extending from the door, a rolleron said shaft disposed. for-eng gaging one of the flanges of the tracksectionfor limiting lateral play of the door, and a wedge blo'ckin thep. th of movement of the shaft during edgewise travel of the door, theshaft extending beyond the roller in position for engaging the block forbeingshifted laterally and correspondingly shifting the door, the wedgeblock being out of the path of the roller.
